Marie Curie and her husband Pierre spent nearly four years boiling down seven tonnes of pitchblende in a leaky Paris shed with no ventilation to isolate one-tenth of a gram of radium chloride, and the notebooks she kept during those years are still so radioactive they are stored in lead-lined boxes at the Bibliothèque nationale.

Two Asian mantis species just got Europe’s harshest invasive label — and the reason involves cannibalized native males, vanishing pollinators, and a warming climate quietly opening the door north

Every year, a single bristlecone pine named Methuselah in California’s White Mountains adds another ring to a trunk that has been growing since roughly 2833 BC, meaning the tree was already 300 years old when construction began on the Great Pyramid at Giza.

Bananas are naturally slightly radioactive because they are rich in potassium, and the dose is so measurable that scientists half-jokingly use the ‘banana equivalent dose’ to explain how small everyday radiation exposures really are

Columbia researchers combed through 9,000 patient records and found a link between the most prescribed antidepressants and faster-failing heart valves — but only in people whose valves were already breaking down

In 1869, a young Swiss chemist named Friedrich Miescher started collecting pus-soaked bandages from a nearby surgical clinic, dissolved the white blood cells, and isolated a strange phosphorus-rich substance from their nuclei that he called nuclein — the molecule the world would spend the next 75 years failing to recognise as DNA.

The Roman Pantheon’s unreinforced concrete dome has stood for nearly 1,900 years and remains the largest of its kind on Earth, partly because its builders mixed in lighter volcanic rock near the top and left a 27-foot hole open at its center.

Wombats produce cube-shaped droppings, the only animal known to do so, forming the flat-sided pellets inside the last stretch of their intestines and stacking them on rocks and logs to mark territory in a way round droppings would simply roll away from.

Iceland’s Hallgrímskirkja church took 41 years to build and was designed to echo the basalt lava columns that cool into hexagonal pillars across the island, so its concrete facade rises in stepped ridges meant to mimic the very rock the country is made of.

A tiny crustacean called Cymothoa exigua enters a fish through its gills, severs the blood vessels of its tongue until the organ withers away, and then latches onto the stub to serve as a functioning replacement tongue for the rest of the fish’s life.

In 1856, an 18-year-old chemistry student named William Perkin was trying to synthesize quinine at home over Easter when a black residue in his flask yielded mauveine, the first commercially successful synthetic organic dye, and helped launch the modern chemical industry

In 1847, Hungarian obstetrician Ignaz Semmelweis watched maternal deaths fall from 18% to about 2% after ordering doctors to wash their hands — but medicine resisted the evidence, and his life ended in an asylum
